I am very new to the iOS Application development and I have been following tutorials to build my career . So starting with I am trying to Implement Static Quick Actions in Objective C as per client project . I was able to add the keys and got the options while pressing the icon . But when I press the Quick Actions nothing happens and it just launches the Application. I have researched a lot and I tried but in vain. Below is the Appdelegate code which I have written:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
BOOL shouldPerformAdditionalDelegateHandling = YES;
// Check API availiability
// UIApplicationShortcutItem is available in iOS 9 or later.
if([[UIApplicationShortcutItem class] respondsToSelector:@selector(new)]){
NSLog(@"HERE");
// [self configDynamicShortcutItems];
// If a shortcut was launched, display its information and take the appropriate action
UIApplicationShortcutItem *shortcutItem = [launchOptions objectForKeyedSubscript:UIApplicationLaunchOptionsShortcutItemKey];
if(shortcutItem)
{
NSLog(@"shortcut launch");
// When the app launch at first time, this block can not called.
[self handleShortCutItem:shortcutItem];
// This will block "performActionForShortcutItem:completionHandler" from being called.
shouldPerformAdditionalDelegateHandling = NO;
}else{
NSLog(@"normal launch");
// normal app launch process without quick action
// [self launchWithoutQuickAction];
}
}else{
// Less than iOS9 or later
// [self launchWithoutQuickAction];
}
return shouldPerformAdditionalDelegateHandling;
}
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler{
NSLog(@"performActionForShortcutItem");
BOOL handledShortCutItem = [self handleShortCutItem:shortcutItem];
completionHandler(handledShortCutItem);
}
/**
* @brief handle shortcut item depend on its type
*
* @param shortcutItem shortcutItem selected shortcut item with quick action.
*
* @return return BOOL description
*/
- (BOOL)handleShortCutItem : (UIApplicationShortcutItem *)shortcutItem{
BOOL handled = NO;
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
if ([shortcutItem.type isEqualToString:@"PlayMusic"]) {
handled = YES;
NSLog(@"Play");
secondview *vc = [storyboard instantiateViewControllerWithIdentifier:@"second"];
self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
}
else if ([shortcutItem.type isEqualToString:@"StopMusic"]) {
handled = YES;
NSLog(@"Stop");
// ThirdViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"thirdVC"];
//
// self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
}
return handled;
}
However I can see the Quick Action items when I deep press the home icon but on clicking that no action happens. I check the key in info.plist and its the same . Quick Actions
Below is the info.plist for adding Static Actions
<key>UIApplicationShortcutItems</key>
<array>
<dict>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypePlay</string>
<key>UIApplicationShortcutItemTitle</key>
<string>Play</string>
<key>UIApplicationShortcutItemSubtitle</key>
<string>Start playback</string>
<key>UIApplicationShortcutItemType</key>
<string>PlayMusic</string>
</dict>
<dict>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypePlay</string>
<key>UIApplicationShortcutItemTitle</key>
<string>STOP</string>
<key>UIApplicationShortcutItemSubtitle</key>
<string>Stop playback</string>
<key>UIApplicationShortcutItemType</key>
<string>StopMusic</string>
</dict>
Can some one please help where I am doing wrong?
since iOS(13.0, *) AppDelegate handles its own UIWindow via SceneDelegate's and so the method
@implementation AppDelegate
-(void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
{
// here shortcut evaluation below ios(13.0)
}
@end
is only invoked on iPhones or iPads with iOS lower Version 13.0
So to make it work in iOS(13.0,*) and above you need to implement it in SceneDelegate with a slightly different name, see below.. (matt was right!)
@implementation SceneDelegate
-(void)windowScene:(UIWindowScene *)windowScene performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler {
// here shortcut evaluation starting with ios(13.0)
NSLog(@"shortcutItem=%@ type=%@",shortcutItem.localizedTitle, shortcutItem.type);
}
@end
PS: The Apple Example Code for Quick Actions in swift is bogus when you assume you can use it as is in iOS(13.0,*) because it is written for versions earlier iOS < 13.0
EDIT: as asked, here in full beauty for iOS >= 13.0
@interface SceneDelegate : UIResponder <UIWindowSceneDelegate>
@property (strong, nonatomic) UIWindow * window;
@end
and
-(void)windowScene:(UIWindowScene *)windowScene performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler {
/* //go to Info.plist open as Source Code, paste in your items with folling scheme
<key>UIApplicationShortcutItems</key>
<array>
<dict>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypePlay</string>
<key>UIApplicationShortcutItemTitle</key>
<string>Play</string>
<key>UIApplicationShortcutItemSubtitle</key>
<string>Start playback</string>
<key>UIApplicationShortcutItemType</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER).Start</string>

<dict>
<key>UIApplicationShortcutItemIconType</key>
<string>UIApplicationShortcutIconTypePlay</string>
<key>UIApplicationShortcutItemTitle</key>
<string>STOP</string>
<key>UIApplicationShortcutItemSubtitle</key>
<string>Stop playback</string>
<key>UIApplicationShortcutItemType</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER).Stop</string>
</dict>
</array>
*/
// may look complex but this is 100% unique
// which i would place $(PRODUCT_BUNDLE_IDENTIFIER). in front of types in Info.plist
NSString *devIdent = [NSString stringWithFormat:@"%@.",NSBundle.mainBundle.bundleIdentifier];
if ([shortcutItem.type isEqualToString:[devIdent stringByAppendingString:@"Start"]]) {
completionHandler([self windowScene:windowScene byStoryBoardIdentifier:@"startview"]);
} else if ([shortcutItem.type isEqualToString:[devIdent stringByAppendingString:@"Stop"]]) {
completionHandler([self windowScene:windowScene byStoryBoardIdentifier:@"stopview"]);
} else {
NSLog(@"Arrgh! unrecognized shortcut '%@'", shortcutItem.type);
}
//completionHandler(YES);
}
-(BOOL)windowScene:(UIWindowScene *)windowScene byStoryBoardIdentifier:(NSString *)identifier {
// idear is to return NO if build up fails, so we can startup normal if needed.
UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
if (story!=nil) {
UIViewController *vc = [story instantiateViewControllerWithIdentifier:identifier];
if (vc!=nil) {
if (_window==nil) _window = [[UIWindow alloc] initWithWindowScene:windowScene];
_window.rootViewController = vc;
// .. OR following code..
//[_window.rootViewController presentViewController:vc animated:YES completion:^{ }];
//[_window makeKeyAndVisible];
// should be success here..
return YES;
}
}
// no success here..
return NO;
}
You can do also other things than instantiate a ViewController from Storyboard. In example you could switch a property or something similar.
